利润折现法比选矿山运输方式

Comparison of Ore Concentration Transportation Methods Using Profit Discount Method

摘要: 为了对矿山运输进行科学合理的比选决策，针对矿山运输方式比选参与比选指标多、技术经济指标不易反映到同一维度，参与比选的方案不易甄别等问题，进行了比选方法研究。采用利润折现法把所有备选方案中的建设投资、年运营费、方案带来的直接收益等因素综合考量，并叠加以各方案投资和收益的资金时间价值，得到参与比选各方案在一定年限内的总利润折现值，其值最高者为最优方案。利润折现法为矿山运输方式比较和甄选构建了一套全新的评价体系，把难以甄别的不同方案反映到同一维度形成差异化并直观区别显现出来，为决策者提供可衡量的尺度。采用利润折现法充分考虑了参与比较各方案投资、运营费和收益的资金时间价值效应，所得到的比选结果更客观真实。

Abstract: To make scientifically sound decisions in selecting the most suitable mine transportation method, a comparative evaluation methodology was developed to address challenges such as the multiplicity of evaluation criteria, the difficulty of aligning technical and economic indicators within a unified framework, and the complexity of distinguishing among competing alternatives. The Profit Discounting Method was employed to integrate key factors from each candidate option—including capital investment, annual operating costs, and direct economic benefits—while accounting for the time value of money associated with both investments and returns. This approach yields a total discounted profit value for each alternative over a defined time horizon, with the highest value indicating the optimal choice. By establishing a novel evaluation system for mine transportation comparisons, the Profit Discounting Method translates previously incomparable alternatives into a unified metric that highlights their differences in an intuitive manner, providing decision-makers with a quantifiable basis for selection. Furthermore, by fully incorporating the time value of money across investment, operational, and revenue components, this method delivers more objective and realistic comparison outcomes.
